Dr. Lénia Amaral presents her research on tDCS and cognitive processing in the NeuroAdx Lab meeting

Today, our lab had the pleasure of welcoming Dr. Lénia Amaral for a talk entitled Boosting Cognitive Processing with tDCS: Lessons from Hand and Tool Representations.

Dr. Amaral presented her work investigating how transcranial direct current stimulation (tDCS) can modulate the neural processing of hands and tools—two conceptually related categories represented within the human semantic system. Using a combination of tDCS, functional magnetic resonance imaging (fMRI), and visual categorization tasks, the study examined how stimulation of the posterior middle temporal gyrus (pMTG) influences category-selective neural representations.

This talk sparked an engaging discussion on the mechanisms of non-invasive brain stimulation, the interpretation of neural modulation effects, and the opportunities and challenges of integrating tDCS with neuroimaging methods to better understand human cognition.

We sincerely thank Dr. Lénia Amaral for sharing her research with our team and for an excellent and thought-provoking discussion.
